… 'Unreleased' The feature was added to the codebase _after_ `1.8.0-beta.1` had already been cut. It should be made available in the next release instead, which is why it should be in the "Unreleased" section of the changelog. This was originally introduced in: - [sdk-traces] Add support for OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG (open-telemetry#5448) (76cafe5)
